Offset of a plane?

[ghost]

Hi,
I was reading: http://www.open3d.org/docs/release/tutorial/geometry/pointcloud.html#Vertex-normal-estimation
for normal estimation.

Now I need to offset a plane from a first plane, using the normal result of the first plane. So I want two parallel planes.

It is not clear how I can achieve that.
Once you get the normal vector of the first plane, what step need to be done to place the other plane in its right position, at a given offset?
Any insight would be helpful.

Thanks

I am afraid my question was stupid, once you get the normal vector just translate the points accordingly..
